Isn't it the same way that you'll find out about triathlete deaths? We read (or have read) about a cycling fatality, do some research online to find out if the cyclist was "like us" and let you know/add to database. I read today about a cyclist killed while cycling to work last week in the town where I grew up. Looks like he died from brain trauma. Happened early in the morning and could have been a hit and run. I found a couple of articles about the accident, found out via a search that he was registered for the current National Bike Challenge and had done a couple of 100+ mile days in the past two months. I doubt he has ever done a triathlon but I'm guessing he paid as much attention to safety as the average triathlete. I could see from photos that he had a mirror on his bike. It looks like he did most of his recreational riding on multiuse trails, so he might not have been wearing a helmet during his final ride. That's the only question I have at this point whether he was a cohort of mine, since I also commute to work via bike.
